Exams and Tests
Diagnosis of
cleft lip is based on a
physical exam of your baby's mouth. Cleft lip usually
is obvious at birth because of distinctive facial characteristics. A baby with
cleft lip should be examined carefully for the presence of other birth defects,
such as
cleft palate.
If cleft lip occurs with
cleft palate, it is sometimes associated with another health condition, such as
fetal alcohol syndrome or
chromosomal disorders. For this reason, it is
important for children to be evaluated for other conditions beginning at birth,
especially if other symptoms are present, such as other facial deformities or
learning disabilities.
Some children with cleft lip may need
testing for complications, such as speech and hearing problems.
Early detection
Fetal
ultrasound can sometimes detect cleft lip as early as 14 to 16 weeks of
gestation. But fetal ultrasound is not reliable for this purpose. Cleft lip may
go completely undetected or its appearance on the ultrasound may be
misinterpreted.
Cleft lip or cleft palate can be passed down
through families (inherited). If you have a family history of cleft lip or
cleft palate, you may benefit from
genetic counseling. A
genetic counselor can help you understand your
chances of having a child with a cleft lip or cleft
palate.
Sometimes an inherited disease or condition causes
a number of defects that includes cleft lip and/or cleft palate. If you have
had a fetal ultrasound that shows your
fetus is likely to have cleft lip and/or cleft palate
along with other defects, you may decide to have genetic counseling along with
amniocentesis or
karyotype testing. These tests and genetic counseling
can help you learn whether your fetus is likely to have a condition caused by
chromosomes that aren't normal. Karyotype testing can also be done after your
baby is born.
